46th Constitutional Amendment Act, 1982

The 46th Constitutional Amendment Act, 1982 is one of the most significant economic amendments in the history of the Indian Constitution.
It was passed to clarify and strengthen the power of both the Central and State Governments to levy taxes on the sale or purchase of goods — particularly in complex business transactions such as works contracts, hire-purchase, hotel supplies, and transfer of goods during service agreements.

Before this amendment, there were many court disputes about whether such transactions could be taxed as a “sale.” The Supreme Court had given several judgments that limited the ability of states to collect sales tax on certain types of composite or mixed transactions.
To remove this confusion and prevent revenue loss, Parliament passed the 46th Amendment to broaden the definition of “tax on the sale or purchase of goods.”

This amendment made sure that the States could levy tax on goods even if the transaction was not a simple sale, and that both Central and State Governments had clear and independent taxation powers.

Background: The Problem Before the 46th Amendment

Before the 46th Amendment, the Constitution (Article 366(29A)) defined “tax on the sale or purchase of goods” in a narrow sense.
A “sale” was understood as a transaction where ownership of goods was transferred from one person to another for a price.

However, many commercial transactions involved transfer of goods as part of services or contracts, not as standalone sales.
For example:

1. Works contracts – like construction of buildings or manufacturing of goods using supplied materials.

2. Hire-purchase agreements – where goods are given on hire and ownership transfers later.

3. Lease or transfer of goods for use – where ownership does not immediately change.

4. Supply of food or drinks in hotels/restaurants – where the transaction includes both goods and service.

5. Job work or processing contracts – where one party processes goods belonging to another.

In all these cases, the question arose:
👉 “Is this a sale of goods or a contract for service?”

The Supreme Court’s judgment in the case of State of Madras v. Gannon Dunkerley & Co. (1958) created a major issue.
The Court held that in a works contract, there is no sale of goods, because materials used in the construction are not sold separately — they become part of the building.
Hence, States could not impose sales tax on such transactions.

This interpretation caused huge revenue losses for State Governments, since many businesses and contractors escaped sales tax by calling their transactions “service contracts.”

To correct this, Parliament decided to amend the Constitution through the 46th Amendment Act, 1982.

Objective of the 46th Amendment

The main objectives of the 46th Amendment were:

1. To expand the scope of taxation on the sale or purchase of goods.

2. To empower States to levy sales tax on transactions that are not pure sales but include a transfer of goods.

3. To remove ambiguity created by Supreme Court judgments such as Gannon Dunkerley’s case.

4. To ensure revenue stability for both Central and State Governments.

5. To bring clarity and uniformity in tax laws across India.

In short, the 46th Amendment was meant to close tax loopholes and make sure that every transaction involving goods — even if mixed with services — could be taxed properly.

Main Provisions of the 46th Constitutional Amendment

The 46th Amendment made changes primarily to Article 366, which defines important constitutional terms.
It inserted clause (29A) into Article 366.

1. Article 366(29A) – Expanded Definition of “Tax on Sale or Purchase of Goods”

This clause listed six categories of transactions that would now be considered “deemed sales” for the purpose of taxation, even though they were not traditional sales.

These included:

1. Transfer of property in goods involved in works contracts.
   (Example: building construction contracts, printing, fabrication.)

2. Transfer of goods on hire-purchase or installment system.
   (Example: buying a vehicle on EMI basis.)

3. Delivery of goods by one person to another for use, without transferring ownership.
   (Example: leasing of machinery.)

4. Transfer of right to use any goods.
   (Example: renting a car, equipment, or software.)

5. Supply of goods by an unincorporated association or club to its members.
   (Example: goods sold by a club to its members.)

6. Supply of food or drink (whether as part of a service or not) for consideration in hotels, restaurants, or catering services.
   (Example: eating in a restaurant or ordering room service in a hotel.)

By defining these as “sales,” the amendment allowed States to levy sales tax on all of them.

2. Clarification of Taxation Power Between Centre and States

The amendment ensured that:

• States could impose sales tax on the sale or purchase of goods (including the newly defined categories).

• Parliament continued to have powers under Article 269 and Entry 92A of the Union List to tax inter-state sales.

• The Central Sales Tax Act (CST) would still apply to inter-state transactions.

This maintained the balance of taxation powers between Centre and States.

---

3. Validation of Certain State Laws

The amendment also validated certain sales tax laws passed by states earlier, which had been declared unconstitutional by courts on the basis of the Gannon Dunkerley judgment.

This meant that past taxes collected under such laws became legally valid, protecting states from refund liabilities.

---

Why the 46th Amendment Was Necessary

The amendment was needed mainly because the judicial interpretation of the word “sale” had become too restrictive. The Gannon Dunkerley judgment and similar cases had prevented States from taxing transactions that were essentially sales in practice, even if not in form.

This caused:

• Revenue loss to States

• Unequal tax treatment between different types of transactions

• Confusion for businesses about their tax obligations

The 46th Amendment simplified this by clearly defining what types of transactions would count as “sales” for taxation purposes.

Impact of the 46th Amendment

The 46th Amendment had a major and lasting impact on India’s taxation system:

1. Increased Revenue for States
   States could now tax several categories of mixed or composite transactions, increasing their revenue base.

2. Legal Clarity
   The amendment removed ambiguity and ended continuous court battles over what counted as a sale.

3. Better Regulation of Business Transactions
   Both businesses and tax authorities now had a clear understanding of tax liability in complex contracts.

4. Foundation for Modern Taxation
   The amendment laid the groundwork for future systems like Value Added Tax (VAT) and Goods and Services Tax (GST), where both goods and services are taxed.

5. Balanced Federal Tax System
   It maintained a balance of power between Centre and States, ensuring both could collect taxes effectively.

Criticism of the 46th Amendment

While it achieved its main purpose, the amendment also faced some criticisms:

• It blurred the distinction between goods and services, which later created difficulties in double taxation (a problem later solved by GST).

• It gave very broad powers to States, which sometimes led to overlapping taxes.

• It was seen as a quick-fix solution rather than a long-term reform.

However, it was still necessary at that time to protect the fiscal interests of the States.

Example to Understand Easily

Let’s say a company signs a contract to build a bridge.
Before the 46th Amendment, the company could argue that this was a works contract (service), not a sale, and avoid paying sales tax on materials used.

After the 46th Amendment, even if the materials (steel, cement, etc.) are used as part of a construction contract, the transfer of those goods is considered a deemed sale.
Hence, sales tax applies to the value of materials used in the project.

---

Significance of the 46th Amendment

The 46th Constitutional Amendment Act, 1982 is significant because it:

• Expanded the definition of “sale of goods” to include various complex transactions.

• Protected State revenues and clarified taxation rights.

• Resolved long-standing disputes between judiciary and government over sales tax.

• Paved the way for future integrated tax reforms like GST.

It represents how the Constitution adapts to economic and commercial realities.

Conclusion

The 46th Constitutional Amendment Act, 1982 was a turning point in India’s taxation history. It redefined the concept of “sale of goods” by including many kinds of composite transactions as “deemed sales,” allowing both the Centre and States to tax them appropriately. It closed legal loopholes, strengthened federal finance, and provided clarity to businesses and tax authorities.

In simple words:

The 46th Amendment made sure that if goods are transferred in any way for a price — even as part of a service — they can be taxed as a sale.

It balanced economic practicality with constitutional principles, ensuring a stronger and fairer taxation system for India.
